Abstract: A random access bubble memory directs a plurality of continuous streams of bubbles toward a plurality of storage loops (42A, 42B, 42C). A write decoder (16A, 16B, 16X) selects one continuous stream of bubbles. An annihilator (30A, 30B, 30X) then transforms this one continuous stream of bubbles into the desired data pattern which is then stored in a selected loop. While the data pattern is being formed, a read decoder (44A, 44B, 44X) directs the data which had been stored in the selected loop to a bubble detector (52). This memory has a unified read/write cycle which permits intermixed read and write, read/modify/write, and swap operations. This bubble memory allows a user to remove power abruptly during a read/write cycle without returning a partially processed block to its storage loop and without saving the identity of the block. In a preferred embodiment, the read and write decoders are operated simultaneously by identical control currents.

Abstract: A process for producing lower alkyl amines by reacting a gaseous alcohol with ammonia at a temperature of from 177°C to 260°C in the presence of hydrogen and a catalyst comprising a Group 8 metal carried on an alumina support is characterized in that the alcohol is a lower alkanol and the support has been rendered neutral or substantially neutral by the incorporation therein of a basic material containing an alkaline earth metal. By neutralising or substantial neutralising the support the amount of hydrocarbon by product formed is reduced thereby increasing the effect life of the cataiyst. 
     Further reduction in the amount of hydrocarbon produced can also be achieved by varying the ratio of lower alkanol to ammonia to hydrogen and ratios of 10-16/1 /0.25-1 seem particularly suitable.

Abstract: In an exemplary embodiment, the simultaneous intensity control of the individual current circuits is to be effected while avoiding undesired intensity deviations in the current circuits such as occur because of nonuniformity of multiple potentiometers, for example. Expediently, the signal frequencies are digitally generated. According to the disclosure, in every output current circuit a transistor is connected-in, which is switched between a conducting and a nonconducting condition so that the collector output exhibits either a zero value or an operating voltage value, all switching transistors being activated on the collector side via a common control element from a single voltage source. In the through-connected state, the collector voltages of the switching transistors have the same value, respectively, which can be synchronously varied in dependence upon the setting of common control element.
